If your Suzuki is a sedan you would need the Curt Hitch item # C11446.
If you are planning on towing you will also need a wiring harness item # 56002 and the Draw-Tite Drawbar item # 3593 and then for hitch balls item # 19258 for a 2 inch ball or item # 19256 for a 1-7/8 inch ball. view full answer...
I went to our warehouse and pulled a Yakima FrontLoader Wheel Mount Bike Carrier, part # Y02103 to get the measurement you asked about.
